Auto switch

[nfsus]

I'm testing an automatic switch I've designed. This version has 3 transceivers hooked to one antenna. It automatically switches during transmit to the radio you've keyed. Once you've let off the key all 3 return to recieve mode. 100w capable. I still have some testing and rearranging of the components on the front of the enclosure. Works very well.

RF sense switching? Sequencer for proper delay?

Yes. Every time I add another step it has to be rethought. But I used the prototype format few weeks between my sdr, ft847 and grant xl on 10 and 11m.
